Hair: shampoo frequency - Christophe Nicolas Biot Paris

While the frequency of shampooing depends mainly on the quality and type of your hair, one thing's for sure: don't wash your hair every day!

Why not wash every day?

There's often a tendency to accelerate the frequency of shampooing, to the point of washing once a day, when we feel our hair isn't looking its best. But this only accentuates the problems. Hair becomes brittle because repeated shampooing strips the hair fiber of its natural protection, making it very fragile. What's more, frequent washing dries out the scalp, which is where dandruff first appears. Or, on the contrary, depending on the type of scalp, it will excite the sebaceous glands and the hair will become greasy. It then becomes very difficult to turn back. Even if you're entering a vicious circle, it's important to rethink your shampoo ritual and give yourself time to get your hair used to fewer washes.

Shampooing frequency according to hair type

Dry or curly hair: one shampoo a week is more than enough. These hair types produce less sebum. If you wash your hair too often, you run the risk of drying it out even more. Tip: If, however, you feel the need to wash your hair a second time during the week, opt for co-washing: use a conditioner instead of a shampoo. The product won't lather, but you can massage it into your scalp before rinsing thoroughly.

For oily hair: you can shampoo two or three times a week, but no more. Washing more often will stimulate the sebaceous glands. The scalp will then secrete sebum and the hair will become greasy more quickly. Tip : On other days, you can run your hair under the water and gently massage the scalp without using any product. Alternatively, opt for a dry shampoo. It will absorb excess sebum and give your hair a fresh look.

Normal hair : three days between shampoos is fine. This will give your hair time to benefit from its natural protection, without saturating it. If you shampoo your hair more often, you'll dry out your lengths.
